The Noctua NH-D9 DX-3647 4U is a high-performance CPU cooler designed specifically for Intel Xeon processors with LGA3647 sockets. It is tailored for use in compact systems like 4U rack servers, where space is limited but cooling efficiency is crucial. The dual tower design with six heatpipes ensures effective heat dissipation, while the two NF-A9 fans provide both quiet operation and strong airflow when needed. This cooler is ideal for users who need reliable cooling in tight spaces without compromising on performance.

The cooler features a contact base measuring 70 x 56 mm, which is significantly larger than standard models, allowing for better thermal conductivity. This, combined with four heatpipes and specially sized fins, ensures efficient heat transfer from the CPU to the cooling system. The dual fan setup includes push and pull configurations, which help in maintaining consistent airflow across the CPU. The NF-A9 fans support PWM for automatic speed control, making the cooler adaptable to different workload demands.

Installation is made easier with the SecuFirm2 mounting system and included processor clips, ensuring a secure and straightforward setup. The pre-applied NT-H1 thermal compound further simplifies the process by providing optimal thickness for the contact surface. This eliminates the need for additional thermal paste application, saving time during installation. The cooler is compatible with a range of Intel Xeon Scalable and Xeon-Phi platforms, including various generations of Skylake-SP and Purley processors.

The Noctua NH-D9 DX-3647 4U is built to last, backed by a 6-year manufacturer’s warranty that reflects the brand’s confidence in its product quality. It is designed for users who prioritize reliability and performance in server environments or compact builds. The compact height of 134mm ensures compatibility with PCIe components, making it suitable for systems where space constraints are a concern.
